The matter in your body makes up less than one trillionth of all the matter on earth,
and the earth makes up less than 1% of all the matter in the solar system. Our star is 1 of 5 billion
in this galaxy, and this galaxy is 1 of 5 million that we know about. If you live to be 100 years old
you will have lived less than one billionth of the age of the universe, and in 5 billion years, assuming
that any sentient beings exists, it is very unlikely that they will have the technology to know that our star,
let alone this planet, ever existed.
